HlNGE.

SPECIFICATION forming part of Letters Patent No. 364,290, dated June 7,1887. Application filed November 12:1886. Serial No. 218,735. CModel.)

To (LZZ whom it may concern:

Be it known that I, Josnrn H. P11311012, a citizen of the United States,residing at Glen- Wood Springs, in the county of Garfield and State ofColorado, have invented certain new and useful Improvements in Hinges;and Ido hereby declare the following to be such afull, clear, and exactdescription of the same as will enable others skilled in the art towhich itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon.

My invention relates to improvements in door-hinges, and aims to providea hinge of such construction that the doormay be opened in eitherdirection and may be set at any desired angle across the thresholdwithout changing the hinges.

The invention consists in certain novel features hereinafter describedand claimed.

In the accompanying drawings, which fully illustrate my invention,Figures 1 and 2 are I side elevations taken from opposite sides; and

Fig. 3 is ahorizontal sectional View of a door provided with my improvedhinge, the several positions of the door being indicated by dotted linesin Fig. 3. Fig. 4 is a detail perspective view of the hinge.

Referring to the drawings by letter, A designates the door, and B thedoor-frame.

G designates the hinge, which is composed of two leaves or sections, DE, similar in size and construction to the ordinary hinge in common use.

Fis a leaf or section of a length equal to the thickness of the wall ordoor-janib, and G is an arm or leaf which extends from the outer edge ofthe leaf or section Fto thccentral line of the door, at which point theyare pivotally connected thereto. The several leaves or sections of thehinge are flexibly connected by means of pintle-pins I-I, insertedthrough loops or eyes formed on their contiguous edges.

The section D is secured to the door-frame in the usual manner by screwsor similar devices, and is provided in its upper edge with anotch, d,thepurposeof which will presently appear. The section E is provided inits upper edge with a similar notch ,c, which is formed at such a pointthat when the two sections are brought together the notches (l cwillcoincide.

The outer end of the section G is provided at its upper and lowercorners with the vertical extensions g, which serve as journals for thehinge.

I I are bearing-plates. which are secured rigidly to the side of thedoor on its central line. These platcsI are arranged aboveand below theend of the section G, and have the perforated arms 6, which extendoutward therefrom at right angles and are formed integral therewith. Thejournals g of the section G engage the perforations of these extensions2', and thereby pivotally connect the hinge to the door. That edge ofthe door which, when the door is closed, is adjacent to the door-janibto which the section D of the hinge is secured is provided with recessesJ to receive the sec tion E of the hinge. These recesses are faced withmetal, so as to reduce the wear thereon and give a neat finish to thedoor.

K designates a catch which is secured to the door on the side oppositeto that to which the end section of the hinge is secured and at theupper-end of the recess J. This catch consists of a plate, K, secured tothe door, and a hook, K, projecting from the edge of the plate at itsupper end. This hook K engages the notch c in the upper edge of thesection E and enters the notch d in the edge of the section D, thusholding the door to the hinge and at the same convenient height.

In operation, when it is desired to operate the hinge in the same mannerasthe hinges now in common use, the catches K are allowed to engage theupper edges of the hinge-seetions, as before described, when the doorwill jmnb, of the hinge comprisinga series of flexib1y-connectedsections, one end section being fixedly securedto the door-jainb and theother one pivotally secured to the door on the central line of the same,and the catches secured to the side of the door and projecting beyondthe edge thereof to engage the edge of one of the intermediatehinge-sections substantially as specified.
